A new Japanese brand of noodles contains only ten calories in each 200g packet,meaning that they can help you feel full while barely registering on your waistline and helping you stick to your diet.

Made of 96 percent water and containing the Asian ground root konjac,Zero Noodles has flown off the shelves in trials,with advocates claiming that they can reduce the calorie content of a meal by up to 500 and effectively trick their brain into thinking that they have eaten a full meal.

High street health food retailer Holland and Barrett said they sold out within a week when they trialled the high-fibre noodles in selected stores.

Priced at 1.99 pounds per pack,they will now be introduced in 700 stores nationwide.
